CVE-2026-3348: Minhnhut Link Gateway

Medium severity, CVSS 4.4. EPSS: 0.3% chance of exploitation in the next 30 days.

The MinhNhut Link Gateway plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's settings (Description, Title, and other fields) in all versions up to, and including, 3.6.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the redirect page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
